Description

Water use device residual in domestic reverse osmosis equipment.

Object of the invention

The present invention relates to a device for the use of wastewater they produce domestic reverse osmosis equipment, which is usually discarded by the drain.

The object of the invention consists of a device that recovers said wastewater for reuse in a new complete debug cycle.

Background of the invention

Due to the poor quality and bad taste of the water Domestic drinking, more and more consumers choose the installation of reverse osmosis equipment for purification of Water. In this sense, there is a great variety of models and brands of this type of household equipment, easy installation, usually under the sink. These teams provide a clean water, more crystalline and better taste.

Home reverse osmosis equipment usually consist of several previous filters (sediment filters, filters of activated carbon, etc.), an osmotic membrane and a reservoir pressurized where the purified water is stored for consumption at through the corresponding additional tap. Osmosis equipment they work taking advantage of the different osmotic pressures to both sides of the osmotic membrane. The network water pressure itself, or that provided by an auxiliary pump, make the water cross the osmotic membrane passing to the other side, accumulating in the pressurized tank for consumption. This last phase of purification, that is, properly that of reverse osmosis, is a very slow process during which a wastewater is produced that fails to pass through the membrane, and that is usually discarded down the drain. The amount of wastewater that is discarded in this type of reverse osmosis equipment, ranges from 60% to 80%, which represents a substantial waste of drinking water.

Description of the invention

The device for water use residual in reverse osmosis equipment that the invention proposes, Solve the problem described above, by allowing reuse said wastewater in a new purification cycle full.

To do this, and more specifically, the device for the use of wastewater in equipment Domestic reverse osmosis are of the type that comprise several pre-filters, an osmotic membrane and a pressurized reservoir where the purified water is stored for consumption through the corresponding additional tap. The harnessing device of the wastewater is composed of an auxiliary reservoir in the which accumulates wastewater from reverse osmosis, equipped with an outlet that channels the water back to the filters previous osmosis equipment, and a water inlet drinkable from the network, to compensate the water consumed by the pressurized deposit. In this way, the water is recirculated residual, which is fully potable, having been filtered by previous sediment and activated carbon filters.

To control the entry of drinking water from the network to the auxiliary tank, it has a level valve that close the water inlet when it reaches a certain level in the auxiliary tank. However, for security reasons, the auxiliary tank has an emergency overflow connected to domestic drain.

On the other hand, to facilitate installation, maintenance and replacement of the auxiliary tank, both the entrance of water coming from the network, such as the water outlet to the previous filters, are provided with the corresponding keys of He passed.

Finally, indicate that for a team of Household reverse osmosis clearance, reservoir capacity auxiliary is between 5 and 10 liters.

Description of the drawings

To complete the description that is being performing, and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1 shows an outline of the components of a reverse osmosis purification system with pump incorporated as standard and with the device for use of the wastewater object of the invention installed.

Figure 2 shows an outline of the components of a reverse osmosis purification equipment with a coupled pump, and with the device for the use of wastewater object of the invention installed.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as the device for water use residual in reverse osmosis equipment, of the type they comprise several previous filters (1), an osmotic membrane (2) and a reservoir pressurized (3) in which osmotic water is stored for consumption, through the corresponding additional tap (4).

Wastewater that has not gone through the Osmotic membrane (2), is channeled through a duct (5), towards the auxiliary tank (6) in which it is accumulated. Saying auxiliary tank (6) has an outlet that channels again the water, through the duct (7), to the previous filters (1) of the reverse osmosis team, creating a kind of circuit closed. To compensate for osmotized water consumed from the tank pressurized (3), through the additional tap (4), the tank auxiliary (6) is provided with a drinking water inlet (8) from the domestic water network. Drinking water inlet to the auxiliary tank (6) is controlled by a level valve (9), buoy type, which regulates the entry of water according to the Reverse osmosis purification equipment demand.

For security reasons, the auxiliary deposit (6) has an emergency overflow (10) connected to the domestic drain, to evacuate possible surpluses of Water.

To facilitate installation, maintenance and replacement of the auxiliary tank (6), both the water inlet drinking water (8) coming from the network, such as water flow through from the duct (7) to the previous filters (1), they are provided with the corresponding stopcocks (11 and 12).

For optimal operation of the equipment reverse osmosis and device for water use residual, the capacity of the auxiliary tank (6) is comprised between 5 and 10 liters, which is not a problem for your installation with reverse osmosis equipment, usually under the sink.

The start of the debug cycle will be performed opening the stopcock (11) for the network water inlet to the auxiliary tank (6) that will pass through the duct (7) to the filters before (1) and after the osmotic membrane (2). He Osmotized water will be stored in the pressurized tank (3) for later consumption. On the other hand, the wastewater will leave storing in the auxiliary tank (6) to start a new cycle Full debug. When osmotized water is consumed from pressurized tank (3), the level valve (9) will let in water from the network, in the same amount as consumed, to complete the debug cycle.

Depending on the network water pressure, the reverse osmosis equipment will have a pump fitted as standard recirculation (13), as it appears in figure 1. In the reverse osmosis equipment that works directly with pressure of the domestic network, said pump (13) will be incorporated according to It is represented in Figure 2. Activation and deactivation of the debug system is done by providing pressure switches (14) that control the minimum and maximum pressure.
